HAND-OPERATED FIRE-EXTINGUISHER. l i

To all whom t may concern: f

Be it known'that I, CHARLES L. BASTIAN, axcitizen vof the United States, residing at Chicago, in the county offCook andState of Illinois,lhave invented certain new and useful VImprovements in Hand-Operated Fire-Extinguishers, of which the following is a'speciiication. Y Y l v This invention relates to a hand-operated fire extinguisher and has for its principal object the provision of a compact and easily 'y operated means adapted to'contain" a supply of liquid and to ejectV the liquld 1n the form of a stream which may be directedfas desired. i v

'A further object of my invention is the provision in a iire extinguisher ot operatlng means th'ereiork which allows a stream ot' liquid to be directed at will without interering with the ease with which the device' is operated.V Y I Another object of my invention is the provision of a hand-operated fire extinguisher havingits outlet normally closed by aavalve which is automatically andA instantaneously released when the operating means is actuated. Y

A still further object of my'invention is the provision cfa hand-operated -ire extinguisher comprising a. minimum number of4 simple and Y relatively inexpensive parts none of-which are liable to be linjuredby carelessl use or continued neglect or disuse of the device.A

Further objects and advantagesof' my invention will lbe apparent as is better understood by reference tothe following specication when 4'read in connection with the 'accompanying drawing, illustrating the preerred embodiment thereof, in whiche vFigure 1 is a vertical section through the mechanism according to my invention; Fig." 2 is a vertical sectionV through the mechanism in a plane normal tothe plane of]3`ig.1p;v l V Fig. 3 is a detail in elevation of the operating crank and the locking means therefor, and Y Fig. 4 is a detail in elevation ofthe locking means for. 4the crank illustrating'the in Voperative position thereof.` l Y Referringto the drawing, 1 indicatesja casing, which is preferably cylindrical' and closed at either end by theend' members 2 and 3. Supported within. the casing 1 is a l I I. threaded rod 4, one end of whichissdisposed Specification of Letters latent.

vent the lpassage ofliquid into'the nozzle `8 under conditions presently yto-be explained.

Journaled yon the bearing member y6 y,is

bevel pinion' 10 which is supported rby a plate llfsecuredto the end member "3 balls 12 beingdispos'ed' between the pinion 10 and the plate lljto reduce the friction therebetween. A pin 9 on ythe rod 4 engages a slot l10 in the pinion v10 and providesan 'operative connection therebetween. Rotatably mounted lin theVV end member 3 -is a "Si shaft 13 having va bevel gear 14,*preferably formed integrally therewith. and,Y meshing with the pinion 10. A manually `.operable crank 15, having a handle 16,'is'secured'to the lshaft 13 andjserves to rotate theshaft 13. A -gland '17 'prevents the liquid within the casing 1' vfrom i escaping about kthe shaft 13. y i' y Y g ,A plunger 18 threadedly engagesthe'frod 4 and is provided' with an asbestos packing ring 19 held in position by a ring 20 threadedly engaging a iange 21 'of the plunger 18; and a washer 22, alsopreferably of asbestos, is held in position by a resilientmember23 which. isclamped to the plunger 18 by a threaded collar'25. A gland 25 surrounding theV rod 4 vprevents the escape of liquid from theinterior 'of the casing 1. Surrounding thebearing 5 -is a spring 2 7 which engages'the plunger'18v when at the limit of its 'travel` in the direction of the end member 2a'nd7forces the rod 4 upwardly, viewingfFigsl an`d`2-, so that" the j conical end ,7' thereof `engages the vvalve y seat 9l topreventescape-,of liquid from the interior of the casing" 1 to the nozzlef8. Y

The endof the' crank 15 is'notched at 28 (Fig. 3) andis adapted tobe'engaged by Val'fspring-pressed latch 29, slidably mounted in ajcasing 30se`cured to the exterior ofV the Y casing 1. The l' spring 31""no'rmal1ly forces the latch-29,outwa'rdly and owing' to the coniigurationof the end of thev crank 15`it maybe rotated in onedirection but isprevented from rotation in the reverse direction. The latch 29 is provided with av han- Vdle 32 operating in an L-shapedslot 33, in

the casing 30, and Ywhen the handle 32 is disposed in the position indicated in Fig. 4 thelatch 29 is withdrawn from position to engage the end of the crank 15. A threaded plug 34Vin the end member 3 allows access to the interior of the casing 1 so that it may be readily filled with liquid;

It will be noted from an inspection of Figs. 1 and 2 of the drawings that the'rod 4 is slightly shorter than the distance between the end of the bearing 5 and the valve seat9 so that longitudinal movement of the rod 4 is possible. yVhen the casing 1 is to be filled Awith liquid the latch 29 is moved to the position indicated in'Fig. 4 Vandthe crank 15 is rotated in an anti-clockwise direction to'frotate the'rod 4 and movethe plunger 18 to the limit of its travel toward the end'member 2. 'Ihe spring 27 will be "engaged by the plunger 18 andtensioned rection which is possible without disturbing the latch 29 with the result that the plunger 18 movesupwardly, viewing Figs.. 1- and Y 2. Y As soon as the tensiony ofthe spring 27 has been releasedthepressure of the fluid within thev casingV 1 will force'V the rod 4 downwardly, viewing Figs. 1 `and 2, freeing the conical end 7 thereof from the valve seat 9 and the fluid will thereupon issue from the nozzle 8. Upon continued actuation of the crank 15 the plunger 18 will continue to move upwardly until it has forced yall of the liquid from'the casing 1.

It will be'readily understood from the foregoing that the normally closed outlet from the casing 1 is automatically and instantaneously opened by merely rotating'the crank 15 and that no vknowledge of the device other than thatV the crank musty be actuated is necessary in order that the device may beutilized,r for its intended purpose.V The provisionof the latch 29 prevents rotation of the crank in an anti-clock- Wise direction and hence an excited individual attempting to uselthe device can not operate it .except in the proper manner to eject-the liquid from the casing.' The device is extremely simple in construction'and 'can not readily be destroyed by careless use nor does it deteriorate-.with continued neglect or disuse. It is, accordingly, when properly filled with liquid, always ready for imme diate use whenever an emergency arises.

' The. provision of a crank for operating the plunger allows the nozzle of the Vdevice to be directed as desired without interfering in any manner with the operation sincel the Vcasing may be readily heldin and directed Y with one'hand while the other is employed in operating the crank. y

It will be apparent that various changes may be made inthe form, construction and arrangement ofthe parts without departing from thespiritand scope of the invention, or sacricing any of Iits Inaterial'fadvantages, the form hereinbefore described being merely a;preferredembodimentthereoi v VI claim: Y.
